Analog input
There are 16 analog input channels on the board – the resolution of the
APCI-3000
and
APCI-3100
is 12-bit and of the
APCI-3006
and

Overview – time-multiplex system
Up to 16 analog Single Ended or up to 8 analog differential signals can be
connected to the board.
Fig. 8-2: Time-multiplex system
After the signals are transferred over a filter (RC-component) to a
multiplexer (time multiplexed system), they are lead over a programmable
instrumental gain to a 16-bit A/D converter (12-bit for
APCI-3000
and
APCI-3100
).
